Some weight loss experts claim wearing a corset draws in the muscles around the core and helps you sweat out toxins. Other experts say wearing corsets do more harm than good.

“The problem is that when you constrict your waist, your organs have to go somewhere,” said gynecologist Dr. Sarah Gottfried, author of The Hormone Cure. “Corsets push your lungs and liver up, and your intestines down. The result is a smaller waist, but organs are out of their natural placement in your body.”

Kardashian has credited the low-carb Atkins diet for her jaw-dropping 56-pound weight loss, which she achieved in just six months. Kim’s weight-loss plan was a low-carb, high-fat ketogenic diet known for producing rapid weight loss without calorie restriction.

Dietitian Dr. Jeff Volek, a professor at Ohio State University, agrees. “It was nothing short of an epiphany when I changed to a ketogenic diet 20 years ago,” Dr. Volek, author of the Art and Science of Low-Carbohydrate Living, told me. “I felt better, more satiated, and had more consistent energy.”

Kardashian also exercises almost every single day, combining rigorous cardio workouts with strength-training and lots of squats. She is proud of the hard work she has put in, and slammed rumors that she got weight loss or other plastic surgery to slim down.
